Viton O Ring or FKM O Ring
Viton O-rings offer excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals making it excellent for o-ring, gasket and seal materials. Viton O-rings or FKM O-rings, fluorocarbon rubber O-rings provide excellent permeability and compression set resistance.
Viton O-rings (FKM O-rings) have low gas permeability and Viton O-rings (FKM O-rings) are commonly used as gaskets in fuel system sealing applications. Other fluorocarbon compounds can also offer improved resistance to acids, fuels, water and steam
